我试图为ViewModel创建一个编辑器模板，并且我看到Kendo控件在生成后面临着问题。循环生成Kendo DropDownListFor在jQuery中没有正确初始化
这里是ParkingServiceDetail.cshtml文件：
@model List<DA.Services.CarPark.Presentation.Web.Models.ParkingServiceDetailViewModel>
<div id="@ViewData.TemplateInfo.HtmlFieldPrefix" style="margin-top:10px">
<table class="table table-bordered table-striped table-hover" id="grid">
<thead>
<tr>
<th data-field="TerminalId">Terminal</th>
<th data-field="ServiceId">Service</th>
<th data-field="ParkingCardNumber">Card Number</th>
<th data-field="ParkingCardIssueDate">Issue Date</th>
<th data-field="ParkingCardExpiryDate">Expiry Date</th>
<th data-field="ParkingCardGroup">Card Group</th>
<th>Action</th>
</tr>
</thead>
<tbody>

这似乎令人生畏，但只有列表排序的解决方法，因为。这是非常基本的东西。
我最初使用Html.Helpers控件，它们工作正常。但是，我需要管理每行中的几个级联下拉菜单。这就是为什么你在代之后看到脚本标签的原因。
问题在于所有Kendo控件都无法启动窗口小部件。我通过在JS中添加按钮代码后启动它们来解决DatePicker。但他们并不真正依赖，所以很容易。尽管这两次下降我都无法做到。
目前，在运行时，两个下拉菜单转换为Kendo并处于禁用状态，不接受任何输入或通过浏览器调试程序响应任何属性更改。
我已经确认，如果我将JS的位从tr代移动到Add按钮单击后，它可以工作，但我失去了需要创建级联依赖关系的ids。
有没有一些线程时序问题，在Kendo的情况下失败，但不是常规控件？
更新
我确定的主要问题是剑道控件的名字是不是唯一的。在我的答案下面的新代码。这解决了50％的问题。
目前尚不清楚你想要做什么，但很明显，你做了错误的方式。无论您想要做什么都可以使用部分视图和ajax来完成。 – ataravati
